BACKGROUND ART Conventionally, a large amount of attention has been paid to a solar power generating system, and many photovoltaic modules are installed in a structure such as a support structure of a house.

On the other hand, in the case of building a large-scale solar photovoltaic power generating system, a vast space for arranging many modules is required.

Therefore, in countries such as Korea and Japan, where the land area is small and there is a lot of agricultural land, there is a lot of farmland, and there are many places with good light in these farmland.

Thus, on June 05, 2013, Korean Patent Registration No. 10-1274199 (solar cell power generation facility equipped with a crop cultivation greenhouse and its construction method) was proposed,

It includes a greenhouse installed on the ground to form a greenhouse, and a solar cell structure coupled to a vertical support frame of the greenhouse,

The solar cell structure is provided with one or more fans on the north-facing surface, thereby forming an air flow toward the solar cell module by the fan,

The solar cell structure is a structure for generating electricity from sunlight by having a plurality of solar cell modules,

a plurality of solar cell modules;

and a support frame part for supporting the solar cell module so that the light-receiving surface of the solar cell modules is substantially inclined toward the south,

The support frame portion is coupled to the vertical support frame of the greenhouse,

The support frame part was configured to include a vertical frame supported and installed on the upper end of the vertical support frame of the greenhouse.

However, in the conventional greenhouse equipped with solar power generation facilities as described above, while installing a solar module for solar power generation on a part of the upper surface of the greenhouse, light reflected by the natural light is irradiated to the shaded area at the bottom. , there was an inefficient problem in that the solar power generation by a part of the greenhouse could not generate sufficient electricity, so that the cost of the solar power generation facility was hardly recovered.

In addition, solar modules for photovoltaic power generation were installed on the entire upper surface of the greenhouse, but with the structure installed in the entire greenhouse, there is an advantage due to the generation of electricity due to photovoltaic power generation, while the entire lower part is a shaded area. There was a problem in that the function as a greenhouse was hardly generated.

And by installing solar panels on farmland, solar sharing is proposed and implemented while farming on farmland while also carrying out solar power generation.

That is, according to Japanese Patent Application Laid-Open No. 2015-17489, a solar photovoltaic power generating system in which a solar photovoltaic power generating system is installed on farmland is described.

In this farm-cum-solar photovoltaic power generating system, a plurality of struts installed on commercial plants and girders growing in the horizontal direction from the top of the struts and a plurality of solar modules supported at an angle to the girders is provided.

By this farm and solar power generating system (solar photovoltaic power generating system), the inclination angle of the solar module with respect to the horizontal plane is predetermined and is fixed at 10 to 15 degrees with respect to the horizontal plane.

Therefore, since the inclination angle of the panel is fixed in the above farm and solar power generating system, it is not possible to respond flexibly when the type of crops in the farmland change or the amount of insolation changes, of course, When solar modules are installed in the upper part of farmland, if the number of solar modules to be installed is too large, in order to not sufficiently light the crops in the farmland, the growth of crops is not made sufficiently, so that the production of crops is reduced. can think of

On the other hand, if the number of panels arranged in consideration of the growth of crops is limited, there is a problem in that it is impossible to sufficiently secure the amount of power generated by the panels that do not affect the growth of crops.

Thus, Japanese Patent Laid-Open No. 27065387 (package management device and packaging management system) dated April 09, 2015 has been proposed,

A control unit for changing the posture of the photovoltaic panel based on the data of the reference illuminance is provided in the posture changing unit,

In order to acquire the illuminance of the light irradiated to the plant, an illuminance sensor is further provided in the space below the solar power panel to change the posture when the illuminance of the light irradiated to the plant from the control unit is greater than the reference illuminance When the posture of the photovoltaic panel is changed so that the amount of light received by the photovoltaic panel increases, and the illuminance of the light irradiated to the plant is the same as the reference illuminance, the posture changing unit of the photovoltaic panel The posture is maintained, and when the illuminance of the light irradiated to the plant is smaller than the reference illuminance, the posture changing unit is configured to change the posture of the photovoltaic panel so that the amount of light received by the photovoltaic panel is small.

And Japanese Patent Publication No. 29012007 (solar power generation system) dated January 19, 2017 has been proposed,

It is a solar panel installed on the upper part of the farmland,

a light saturation point storage unit for storing the light saturation point of the crops grown in the farmland for each type of the crop;

Provided with an angle changing unit for changing the inclination angle of the light receiving surface of the solar panel with respect to the incident direction of the sunlight,

The angle change unit is configured to change the inclination angle so that the inclination angle approaches a right angle when the amount of solar radiation acquired by the insolation acquisition unit is equal to or greater than the light saturation point stored by the light saturation point storage unit.

In addition, Japanese Patent Laid-Open No. 29145565 (solar power generation system and method) dated August 24, 2017 has been proposed,

It is installed on farmland or farmland, a plurality of photovoltaic panels,

On the other hand, when the cumulative insolation of crops to the farmland exceeds the light saturation point of the crop, the amount of insolation to the photovoltaic panel is maximized. It is configured to dynamically change the inclination of the photovoltaic panel as much as possible.

However, according to the conventional structure and control method in which a solar module is installed on the upper part of agricultural land as described above, it is not possible to check the exact state of photosynthesis by measuring the light saturation point with illuminance, so solar power generation that prioritizes plant growth If this is not done, it may cause problems such as a decrease in crop yield, as well as a problem in that the growth of plants is inhibited compared to other areas in areas shaded by solar modules and structures for installation of solar modules. there was
